Abstract: An electronic traction optimization system includes a control unit adapted to produce a corner speed estimate signal for each wheel of a machine, produce an ideal target speed signal for each wheel having a value at least partially responsive to the corner speed estimate signals, produces a practical target speed signal for each wheel, generates an actual target speed signal having a value responsive to a comparison of the ideal target speed signal and the practical target speed signal for each wheel. The control unit compares each actual target speed signal to an associated wheel speed signal to obtain a wheel speed error signal for each wheel and converts each wheel speed error signal to a clutch control signal, wherein each differential clutch actuator is responsive to an associated clutch control signal.

Abstract: A motor vehicle driveline that can transmits power in a 4×4 mode includes two front wheels, a rear drive shaft, a differential mechanism for transmitting power to two rear axle shafts connected driveably through the differential to the rear driveshaft, and a clutch for engaging and disengaging a drive connection in the differential mechanism. A method for controlling operation of the clutch includes the steps of operating the driveline in 4×4 mode, determining a current accelerator pedal position, determining whether a current accelerator pedal position is less than a reference position for a predetermined period, determining a current speed of each front wheel of the vehicle, determining whether a current speed difference between the front wheels of the vehicle is less than a reference wheel slip for a first predetermined period, determining during a second predetermined period whether a current time rate of speed change of the rear drive shaft is less than a reference rear wheel slip. The clutch is prevented from being engaged if either the speed difference exceeds the reference speed difference, or the time rate of speed change of the rear drive shaft is greater than a reference rear wheel slip. Otherwise, the clutch is engaged.

Abstract: The invention relates to an asymmetrical, active axle transmission with an epicyclic gear system, which is arranged concentrically to a side shaft (7) and has a planet carrier (17). To achieve an active yaw function, the planet carrier (17) or the central wheel (13) can be braked. Conventional asymmetrical active yaw gears use in this connection two separate brake clutches. This enlarges the construction space and increases the manufacturing costs which the invention avoids in that the planet carrier (17) is part of a first brake coupling (5) and that a second brake clutch (9) for braking the side shaft (7) as well as the first brake clutch (5) use a common abutment lamella (19).
